They got like 3 GBs worth of stuff in at one time so they are still making their way through everything. It's slow going but they did set the ship date as November 30th so you should have tracking by then.
You were quite correct, they're dealing with the 3 GB's and the holiday rush. Just gotta hurry up and wait as they say.
Update 12/19/2021: 19 Days past the shipping date for preorders and we're still waiting.
Just for kicks and giggles I ordered extras from Zfrontier and DailyClack with the default shipping speeds after making this post. 2 orders from 2 different vendors shipped through congested ports across the Pacific beat a vendor in the same country as me with a lead time of 3 months.
Un-freaking-believable. What the hell are they even doing over there?
